SUBMARINE OR SUBMERSIBLE TORPEDO-BOAT.

Specification of Letters Patent.

Patented July 15, 1913.

[ alt whom it may concern:

Be it known that I, EDWARD LASIUS PEA- COCK, a subject of the King of Great Britain, at present residingat Bridgeport, in the county of F airfield and State of Connecticut, have invented certain new and useful Improvements in Submarine or Submersible Torpedo-Boats, of which the. following is a specification. e

The invention provides a submarine or submersible torpedo boat that is particularly adapted for coast and harbor defense.

-The main features of'the invention are, first, a peculiar construction of hull where by a'greater number of torpedo expulsion tubes may be installed, and, certain storage and other compartments provided for; and second, an arrangement of the said tubes whereby the torpedoes may be fired in various directions from the boat without maneuvering the boat from its station in the event of hostile vessels approaching from various quarters; and, third, means for anchoring the boat either upon or below 2'5 the surface of the watenand' for swinging the boat in a horizontal direction at its mooring so that all ofthe torpedo tubes may be fired in a given direction in the event of anattack by a-hostile fleet approaching from one quarter only.

The invention consists in these features, singly and in combination, as will be hereinafter fully explained and, claimed.

In the drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a side elevation, Fig. 2 a plan view, and Fig.

3 a bow view of the boat. Fig. 4 is a vertical longitudinal section of the boat, and Fig. 406 is a horizontal section of the same on a larger scale. Fig. 6 is avertical transverse section drawn through the bow, on a larger scale, on the line AA of Fig. 4. Fig. 7 is a detail horizontal section drawn on a larger 46 scale on the line BB of Fig. 6. -Fig. 8 is a section drawn on the ,line CC of 7.

Fig. 9 is a vertical transverse section drawn on a larger scale on the line DD of Fig. 4.

Fig. 10' 1s a horizontal section drawn on the 59 line E-E of-Fig. 6, the battery cells being omitted. Fig.11 is'a'diagrammaticverticallongitudinal section drawn through the bow illustrating adifierent arrangement of they torpedo expulsion tubes. Fig. 12 is a horizontal' section drawn on the line FF of Fig. 11. Fig. 13 is a diagrammatic horizontal section drawn through the bow showing another arrangement of the torpedo expulsion tubes. Fig. 14 is a detail sideeleva- 4 tion of the truck for moving the torpedoes into position to be inserted in the tubes.

Fig. 15 is a vertical longitudinal section of the boat illustrating the arrangement of a rotatable torpedo turret carried by and at the bow end of the boat. Fig. 16 is a horizontal' section drawn on the line G-G of Fig. 15. Fig. 17 is a detail sectional view illustrating one way of holding the rotatable turret to the main j-hull section. F ig. 18 is a similar view illustrating a slightly diflerent construction to that shown in F ig..

11. Fig. 19 is a perspective'view of the construction shown in Figs. 15 and 16. g

The hull (Figs. 1, 2, 4 and 5) is constructed of a substantially globular bow section 1 which is of sufficient strength to withstand the pressure incident 0 subm'ergence, and from this section extends the amidships section 2 of cylindrical form in'cross'section, and from the after end of the amidships section extends the after or stern section 3 which is of gradually decreasing di ameter from the amidships section 2 to the extreme after end of the boat. The sections 2 and 3 are also constructed of sufiicient strength to withstand the external pressure when submerged. All of the said ,sections are constructed of ribs of frames 4 and shell platings 5, the latter being connected to said ribs or frames and to each other in the usual manner. I have purposely omitted the showing of the ribs or frames in the globular section 1 in the diagrammatic figures of the drawings to avoid confusion of the parts and to more clearly bring out the form and arrangement of the hull sections, the torpedo expulsion tubes and other devices arranged in the hull, but it will of course be understood that all of the said sections will be suitably staved'and braced according to the practice followed in the construction of the class of boats to which my invention relates and. I therefore do not wish to be limited to'fsueh details nor do I desire to be limited to t e arrangement of the ribs as shown in the gi'obular section of the hull as the ribs may be arranged either vertically or horizontally without departing from the spirit of the invention.

In order to preserve the lines of the hull and to provide it witha gradually tapering form, from the bow section 1 to the extreme after end of the boat I arrange a fairwater housing or casing 6 around the amidships section 2 that extends forward from the inner or forward end of the after section 3 and has its forward end connected to and extended from the periphery of the globular section 1 on a tangent line. Built upon the housing 6 isa superstructure 6 providing a deck to the boat and the space between the deck and the housing and the space between the housing 6 and the intermediate section 2 are designed to be open to the surrounding water when the boat is submerged and therefore the said deck and housing are made of light weight frames and plating and are not intended to withstand the external pressure as are the main hull sections when the boat is submerged.

The globular section 1 is provided with horizontal partitions or decks 7 which divide the said section into a lower water ballast compartmentS, an intermediate tor pedo' compartment or magazine 9 and an upper compartment 10 which provides a navigating room and otficers quarters. In the lower compartment 8 is arranged a tank .11 that provides a battery compartment for the storage battery cells from which power is derived for operating the boat when below the surface of the water and which communicates with the central torpedo compartment 9 through a hatchway 12 controlled by a hatch-cover 13 opening into the compartment 9. Arranged in the lower side of the shell of the globular section 1 is an opening which is surrounded by a substantially funnel-shape casing 14, Fig. 6, that extends upwardly through the battery compartment 11 and through the lower partition or deck 7 into the central compartment 9, the said casing providing an anchor well for housing a mushroom anchor 15 Sup ported by an anchor cable 16 which extends from a drum 17 arranged in the intermediate compartment 9. The drum isoperated by a suitable motor 18 which is wired to the batteries in the usual manner.

I 19 designates lead ballast arranged in the bottom of the compartment 8.

20 designates the torpedo expulsion tubes located in the central or intermediate compartment 9, and arranged radially in said compartment so as to extend through the hull throughout nearly its entire circumferenoe with their inboard ends arranged sufiiciently far apart to permit of the loading of the tubes, the operation of the firing gear (not shown) and the firing of more than one torpedo at the same time. The

outer ends of these tubes are inclosed in a belt or housing 1' substantially rectangular. in cross-section and which extends entirely around the circumference of the globular section either from the sides of the intermediate hull section 2 or from the sides of the housing or casing 6 to which they are connected. The belt or housing is constructed of light weight frames which are covered by light weight shell plating and the space 21 formed thereby is designed to be open to the sea when the boat is' submerged or to be partly filled with water to trim the boat when it is operating on the surface. The outboard ends of the tubes are covered by caps which are opened and closed by suitable gearing-(not shown) operated from the interior of the boat.

In order to permit the loading of the tubes from the interior of the-boat, I so arrange and group them that they will be out of horizontal or vertical alinement or so grouped that snflicient space is left between the tubes to permit of a torpedo being first moved upbetween any two or more tubes on one side of the compartment into alinement with the tube to be loaded and then moved forwardly into the tube.

In Figs. 4, 5 and 6 I show the groups of tubes on each side of the compartment with their inner ends out of alinement with the inner ends of the tubes on the opposite side of said compartment whereby the tubes may be loaded as stated; but inasmuch as there are no tubes extended through the after side of the hull section 1 the tubes at the bow or forward side may be arranged in any position desired irrespective of the other tubes as sufiicient space is afiorded between the inner ends of the tubes and the the torpedoes being run into the tubes without interference with any of the other tubes.

In Figs. 11 and 12, I show the tubes arranged helically, so that the tubes on one side of the compartment are either above or below those on the opposite side for the same purpose. In Fig. 13 I show still another arrangement of the tubes in which the globular section of the hull is made larger in diameter than the constructions shown in Figs. 4;, 5, 11 and 12, which permits of the spacing of the inboard ends of the tubes far enough apart, about 22 feet, to allow 10 after side of the compartment to permit of way 22 (Fig. 4) extending from the after side of the section 1 up through the deck of the housing 6 and through a hatch 23 arranged in the upper deck 7. This hatch also provides a passage from the interior of the boat to the navigating compartment 10. The inboard and outboard ends of the hatchway 22 are controlled by hatch covers 24 and the hatch 23 is controlled by a Cover 25, which last and the innermost cover 24 open into the navigating compartment.

26 designates a conning tower built upon the top of the globular section 1 in the top of which is arranged a covered hatch 27 through which access to the navigating compartment may be had from the exterior of the boat.

28 indicates observing instruments extended upwardly through the conning tower. It will be understood that the steering wheel and other devices for operating the boat (not shown, but of-any approved construction) will be arranged and controlled from within the navigating compartment.

. The after end of the amidships section 2 is connected to a bulkhead 29 which is arranged at the inner end of the after section 3 and is provided with a door-way 30 through which access may be had to the after compartment in the boat, and within thesaid section 2 adjacent to its forward end is arranged a bulkhead 31 that is provided with a doorway 32 which is surrounded by a flanged casting or casing 33 which connects the said bulkhead with the after side of the globular section 1 and which also surrounds an opening 34 forming a doorway in said globular section 1 which is controlled by a door 35 that opens into the torpedo compartment 9. The amidships section 2 is divided longitudinally by a horizontal floor or partition 36 which extends from the forward to the after bulk head and'the space thus formed below the partition 36 is subdivided by athwartship partitions36' into a series of water ballast compartments into which water is let to partially overcome the buoyancy of the boat when it is to be submerged. Above the partition 36 and forward of the center of the amidships section is arranged a partition or bulkhead 37 that divides the upper space in said section into an engine compartment and a living compartment for the crew. The partition or bulkhead is provided with a door-way 38 that is controlled by a door 39. To the after side of the bulkhead 37 is a11:l gedthe switch-board 37 controlling zontal floor or partition 42 into a lower water-ballast compartment 43 and an upper dynamo and motor compartment, and in which also may be located other appurtenances of the boat. Arranged athwartship adjacent to the after end of the section 3 is a horizontal tubular casing 44 in which is arranged a propeller 45 that is geared to the main motor and by which the after end of the boat may be swung around when the boat is anchored either upon or below the surface of the water, as will be hereinafter explained.

46' designates a hatch-way leading into the engine compartment from the deck of the boat, which l1atch-way is controlled by a hatch cover 47. a

48 designates a pneumatically operated and vcushioned wheel which is adaptedto be projected through the keel of the boat when the boat is operating adjacent to or near the bot-tom. v

50 designates trimmin or submergence rudders or hydroplanes Figs. 6, 7 and 8) arranged in casings 51 located in the space formed by the belt 1', and these rudders are adapted to be extended from the sides of the globular section 1 of the hull. Each of these rudders is connected by a stem or piston rod that extends from a piston 52 \vhich operates in a cylinder 53 also fixed in thespace in the belt 1'. To the opposite ends of the cylinders 53 are connected air pipes 54through which compressed air is supplied to the cylinders upon opposite sides of the pistons for forcing the pistons outwardly and inwardly and likewise the rudders or hydroplanes, when the latter are to be brought into and out of use. The tilting or rocking of the rudders or hydroplanes is controlled by any suitable gearing arranged within the torpedo compartment, and for purpose of illustration I show the inner end of the piston'rod extended into the said compartment and provided with elongated gear teeth whichare meshed by and slidably engage pinions 56 held in supports 57, and which pinions are operated by hand levers 58 as shown. .By this arrangement it will be understood that when the rudders or hydroplanes are to be brought into use air is supplied to the inner ends of the cylinders to force the rudders out beyond the sides of the hull when they may berocked to incline their surfaces to exert either a downward or upward influence to the movement of the boat as it is propelled through the water. I make'no claim to the broad idea of this feature of the boat as its use and operation is well known in submarine boats.

In Figs. 15, .16 and 19, I illustrate a differ ent construction of the globular section of the hull and a different arrangement of the torpedo tubes, anchor and bottom wheel.

.would cause it to sink,

In this form of the hull I construct the substantially globular section 1 with a concaved top 59 andmount therein a rotatable torpedo turret 60 which is substantially elliptical in cross-section and is provided with suitable roller bearings 61 (Fig. 17) which are carried by brackets depending from the lower side of the turret 60 and over the rollers I arrange an annular track or flanged ring 62 fixed to the top 59. This arrangement serves to securely hold the turret in place and at the same time permits of its being rotated. In this construction the bracket supporting the roller bearings may be secured to the rotatable turret in any suitable way whereby the bracket can be released from the interior of the turret so as to permit of the turret being detached in the event of such an accident to the boat as In such case the detachable turret would serve as an escape cage or compartment to the boat.

In Fig. 18 I show a slightly different arrangement in which the roller supports are made in the form of brackets 62 carried by stems that extend upwardly into the rotatable compartment or turret and held in place in a bracket by nuts as shown. Depending from the center of the lower side of the turret is a cylindrical shaft 63 which is journaled in a bearing formed in the top of the concave top-59 and which is provided with a stuffing box and gland to prevent leakage into the interior of the main section of the hull. The lower end of the cylindrical shaft (33 is closed by a head having a hatch-Way controlled by a cover 6% that opens downwardly into the torpedo compartment 9. Arranged within and extending through the shell of the revoluble turret aretwo torpedo tubes 65 and on the top of said section is arranged a conning'tower 66 through the top of which extends a sighting instrument 67 through which the operator takes observations when the hull of the boat is submerged and only the upper endof the instrument projects above the surface of the water. In order-.that the operator may conveniently take observations I mount a chair or platform on the inner ends of the torpedo tubes 65 in such position that the operator may conveniently look through the instru-v ment as shown in Fig. 15. 68 designates a loading hatch-way leading into the turret and controlled by ahatch cover 69. In the lower side of the compartment of thefturret is arranged a horizontal divisional platform and communication between the upper toredo compartment and the main hull is atforded through a hatch-way 70 controlled by covers 71 arranged at each end of the hatchway. The lower or main section of the globular hull section 1 is divided by a horizontal platform or deck 72 below which is suspended a battery compartment 73 which tubes.

is completely surrounded by a water-ballast compartment formed by the deck T2. The space in the hull above the said deck pro vides a torpedo compartment T l in which is arranged a series of torpedo tubes 75 that open through the shell of the hull. The side tubes, as shown in Fig. 16, are arranged out of longitudinal alinement so that the torpedoes may be readily loaded into the tubes as shown in dotted lines. The outboard ends of the. tubes are incased in a belt 76 similar to the belt 1' shown in Figs, -t and In the construction shown in Figs. 15; 16 and 19 the amidships section 2 of the hultis divided by a bulkhead T7. the space between which and the after side of the globular section provides a torpedo storage comparb ment 78 for spare torpedoes; and below this compartment is arranged a storage compartment 79 for the war heads of the torpedoes. Extending upwardly from the amidships section 2 is a navigating turret 80 which communicates with the torpedo storage compartment through a hatch-way 81 controlled by a cover 82. 83 designates a loading hatch opening into the storage compartment through which torpedoes are loaded into the boat.

In the construction shown in Figs. 1 to 'Z inclusive, I show a casing 84 that extends from the upper and lower edges of the belt 1 and entirely surrounds the globular section of the bull to which the casing is connected, thereby providing fair-lines to the bow section of the' boat, the spaces thus formed being designed to be open to the surrounding body of water when the boat is submerged. I do not wish, however, to be limited to the arrangement of the casing as the same may be omitted as shown in Figs.

15, 16 and 17, in which construction the casing is arranged only at the bow to provide fair-lines or a ship-shape bow to the boat. The bow torpedo tubes open into pockets 85 formed in this casing and the outboard covers of the said tubes open in said casing when the torpedoes areto be fired from the This construction provides a deck around the bow of the boat which not only affords an exercising deck for the crew but also a surface to facilitate the handling of the boat when making a landing or when taking on supplies. When the storage battery compartment is suspended from the deck 72' and where the casing or fair-lino section is arranged only at the bow of the boat, I may arrange the wheel 48 and the anchor casing 14 at the extreme bow section as shown in Fig. 15.

As stated; the boat is particularly designed for coast and harbor defense and when stationed to defend the entrance to a harbor or a certain section of the coast, it

will be anchored in surface trim and upon the approach of hostile vessels the will' be submerged until only her observing in- I struments are projecting above the surface of the water, inyvhich condition the boat may be maneuvered until it is how on to the approaching fleet at which the torpedoes are to be fired the moment the vessels of the fleet come within range of the torpedoes, and owing to the arrangement of the tor edo tubes in the boat, whereby the torpe oes may be fired throughout a radius of practically 280, a very great advantage is obtained especially should the fleet approach rom different directions, as practically no maneuvering of the boat is necessary to adjust it into position to fire the torpedoes. However, should a fleet approach in column formation, the boat may (by operating the propeller 45), after discharging the torpedoes from all of the tubes on one side of the boat, be swung around its mooring in either direction so as to bring the loaded tubes into line with the approaching vessels and into the proper firmg position.

It will thusibe seen that I provide a highly eflicient boat of the class described which has an advantage over its class since by its ability to carry a great number of torpedoes, it is independent of a parent ship and at the same time is capable of moving under its own power to any oint or station and of submergence to a sa e depth should a vessel approach within a dangerous zone.

It has been found from experiments that a hull of the shape shown in Fig. 1, that is,

a substantially conical or a spindle-shape hull with a blunt rounding nose or bow provides a very efiicient form for submerged speed, since the blunt -nose or bow gives a minimum wetted surface at the bow and the cone or spindle body a fine run aft and consequently an easy entrance and clearance through the water. Thearrangement of the fairwater' casing forward and aft of the globular section hull.
